How to change the font size of selected text in edittext at runtime?

Question

I am developing a text editor for my application, in which i want to edit the selected portion of text. And i am almost done with it except one feature, that to decrease the size of selected text.

I could increase the size like : text=editor.getText(); text.setSpan(new RelativeSizeSpan(2f), start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); editor.setText(text);

But i am stuck with decreasing the size, How the size of text can be decreased ?

Answer 1

try the same way as you have used for increase textsize used code as shown below where editor is EditText

 Spannable text=(Spannable)editor.getText(); 
 text.setSpan(new RelativeSizeSpan(0.2f), start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);    
 editor.setText(text);

in RelativeSizeSpan i have used 0.2f as a text size which will decrese your textsize you can use what ever size you need accordinglly
